This is a teapot made by Yamada Seisakusho, found while cleaning out a relative's house. It's heat-resistant and can be used directly on a flame. It's from around the 1960s. Although it's a new, unused item, it's dusty overall due to long-term storage. The outer box is quite damaged. It comes with a plastic tea strainer. For 5 servings. It's over 50 years old. Please refrain from purchasing if you are sensitive to such items. No returns accepted.
